看门狗0超时逻辑：
|
||
1. 看门狗0从系统发送下行包时，触发工作；
|
||
2. 系统上行时，停止看门狗工作并复位看门狗计数器；若发生超时，报超时状态，复位继续工作，此时有上行包，不予响应；
|
||
3. 看门狗不使能，则对应的看门狗停止工作，也不会报相关的状态位与中断；
|
||
4. 写对应的看门狗状态寄存器，对应看门狗被复位；需要重新触发才能工作。
|
||
|
||
|
||
SM0/2/4/6与SM1/3/5/7超时逻辑：
|
||
1. 看门狗从读写第一个字节被触发计时工作；第二次读写第一个字节，不影响看门狗工作；
|
||
2. 读写最后一个字节，停止看门狗工作并复位看门狗计数器；若发生超时，报超时状态，复位继续工作，此时系统读到最后一个字节，不予响应。
|
||
3. 看门狗不使能，则对应的看门狗停止工作，也不会报相关的状态位与中断；
|
||
4. 写对应的看门狗状态寄存器，对应看门狗被复位；需要重新触发才能工作。
|
||
|
||
看门狗17超时逻辑：
|
||
1. 看门狗17从系统发送第一个下行包时，触发工作；
|
||
2. 系统发送第二个下行包时，停止看门狗工作并复位看门狗计数器；若发生超时，报超时状态，复位继续工作；
|
||
3. 看门狗不使能，则对应的看门狗停止工作，也不会报相关的状态位与中断；
|
||
4. 写对应的看门狗状态寄存器，对应看门狗被复位；需要重新触发才能工作。
|
||
|
||
|
||
复位继续工作，指看门狗需要重新被触发开始计数直至超时或者复位。写看门狗状态，无论超时没超时，对应bit为1，则对应看门狗被复位。
